Microsoft may not have released any more information regarding the actual changes in the latest version of Windows Vista SP1, but the company has widened the release pool to... everybody. When Microsoft first made the update available earlier this week only about 15,000 beta testers were given official download links. Now you can grab the update as a direct download. You can also download the service pack through Windows Update if you jump through a few hoops.

You'll need to uninstall the previous version of SP1 if you have that installed. Vista SP1 RC Refresh will self destruct (or stop operating if you want to be less dramatic about it) after June 30, 2008. That shouldn't be a problem since Microsoft plans to release the final version of SP1 before then. But make sure you uninstall this update and install the final version of SP1 when it becomes available.
